Allow users to upload an image and attache it to their reviews!
The User Reviews Image add-on adds a new field to the user reviews form to allow your website users to upload and attache an image when submitting a review. If a user uploaded an image, it will show within her/his review.
To add the image field to the user reviews form, all what you have to do is to install and active the add-on on your WordPress website. The add-on will then work automatically on user aggregate reviews.
